Audi Sport Quattro S1

This is one of the cars that Audi took along to the VSCC's Richard Seaman Memorial Trophies meeting at Donington Park in May 2001, together with the Auto Union C-Type and D-Type pre-war Grand Prix cars. The car is seen at Coppice Corner during one of the demonstration runs.

It's an Audi Sport Quatro S1 which was a variant of the Quattro and was developed for homologation for Group B rallying in 1984.  It had an all-aluminium 5-cylinder inline 2,133 cc engine with twin overhead camshafts and 4 valves per cylinder, Bosch fuel injection and a KKK K27 turbocharger.
